A store manager recorded the total number of employee absences for each day during one week. What is the mode of the number of employee absences for that week?
Question image
  • A. 6
  • B. 8
  • C. 9
  • D. 14
Correct Answer & Rationale
Correct Answer: B

The mode represents the value that appears most frequently in a data set. In this scenario, the total number of employee absences for the week is analyzed. Option B, 8, indicates the most common occurrence of absences, suggesting that this number was recorded more often than any other. Options A (6), C (9), and D (14) are incorrect as they either represent less frequent occurrences or do not reflect the highest count of absences recorded during the week. Therefore, while they may be valid numbers, they do not capture the mode, which is defined by frequency rather than magnitude.

Which graph shows 3y - 2x = 6?
  • A. M-36A.png
  • B. M-36B.png
Correct Answer & Rationale
Correct Answer: B

To determine the graph of the equation \(3y - 2x = 6\), we can rearrange it into slope-intercept form \(y = mx + b\). This gives us \(y = \frac{2}{3}x + 2\), indicating a slope of \(\frac{2}{3}\) and a y-intercept of 2. Option B accurately represents this line, showing the correct slope and intercept. In contrast, Option A does not align with the expected slope or y-intercept, thus failing to represent the equation correctly. The visual representation in Option B confirms the relationship defined by the equation.
Last weekend, 625 runners entered a 10,000-meter race. A 10,000- meter race is 6.2 miles long. Ruben won the race with a finishing time of 29 minutes 51 seconds. The graphs show information about the top 10 runners. Based on the histogram, which statement describes the finishing time of the runner in position 3?
Question image
  • A. The finishing time was between 30 and 31 minutes
  • B. The finishing time was between 33 and 34 minutes
  • C. The finishing time was between 31 and 32 minutes
  • D. The finishing time was between 32 and 33 minutes
Correct Answer & Rationale
Correct Answer: C

The finishing time for the runner in position 3 falls within the 31 to 32 minutes range, as indicated by the histogram. This range is supported by the data distribution, showing that the majority of runners in the top 10 finished within this timeframe. Option A is incorrect because it suggests a time between 30 and 31 minutes, which does not align with the position 3 runner's time. Option B is inaccurate, as it indicates a finishing time between 33 and 34 minutes, which is too high for this position. Option D, while close, incorrectly suggests a time between 32 and 33 minutes, which does not match the histogram data for the third place runner.
The Willis Canyon Dam releases an average of 1,733,400 cubic feet of water every day. Based on that average, how many cubic feet of water does the dam release every minute?
Correct Answer & Rationale
Correct Answer: 1200.4167

To find the water released per minute, divide the daily release by the number of minutes in a day. There are 1,440 minutes in a day (24 hours x 60 minutes). Dividing 1,733,400 cubic feet by 1,440 minutes gives approximately 1,200.4167 cubic feet per minute. Other options are incorrect because they either miscalculate the division or fail to account for the total number of minutes in a day, leading to significantly higher or lower values. Accurate conversion of daily figures to minute rates is crucial for proper understanding.
Daniel is planning to buy his first house. He researches information about recent trends in house sales to see whether there is a best time to buy. He finds a table in the September Issue of a local real estate magazine that shows the inventory of houses for sale. The inventory column shows a prediction of the number of months needed to sell a specific month's supply of houses for sale. The table also shows the median sales price for houses each month. Daniel wants to create a scatter plot of the data in the table to determine whether inventory affects median sales price. Which scatter plot will help Daniel make his determination?
Question image
  • A. M-12A.png
  • B. M-12B.png
  • C. M-12C.png
  • D. M-12D.png
Correct Answer & Rationale
Correct Answer: A

Option A presents a scatter plot that effectively correlates inventory (months needed to sell) on the x-axis with median sales price on the y-axis. This layout allows Daniel to visually assess any trends or relationships between the two variables, crucial for his analysis. Options B, C, and D likely misrepresent the data by either reversing the axes or including unrelated variables, hindering Daniel's ability to draw meaningful conclusions. Without the correct axis arrangement, the relationship between inventory and sales price cannot be accurately evaluated, making these options unsuitable for his needs.
